Unhelpful message when unable to iroh start

[expede]

I managed to solve this one myself, but I didn't see an existing Issue for this so figured I'd file it in case someone else runs into something similar in the future.

I think the root cause is that I had some old Iroh files on my system. Here's the relevant parts of my console history (omitting various troubleshooting steps).

$ nix shell nixpkgs/nixos-unstable#iroh

$ iroh --version
iroh-cli 0.14.0

$ iroh start
Error: Table 'records-by-key-1' does not exist

$ rm -r /Users/expede/Library/Application\ Support/iroh/

$ iroh start
Iroh is running
Node ID: <HIDDEN>

This is absolutely an edge case so likely not high priority. It might be nice to either add a better error message (e.g. "you have an existing install and we failed to migrate") or a CLI command to do a completely fresh install (e.g. iroh clean). I knew that this is a Rust project and thus was able to use RUST_LOG, but a --verbose flag may be more familiar to non-Rustacians.

thanks, yes we should improve on these error messages
